Trials of the Cherokee were reflected in their skulls
Wed, 16 Apr 2014 11:29:54 EDT - Researchers have found that environmental stressors -- from the Trail of Tears to the Civil War -- led to significant changes in the shape of skulls in the eastern and western bands of the Cherokee people. The findings highlight the role of environmental factors in shaping our physical characteristics.
Making new materials an atomic layer at a time
Wed, 16 Apr 2014 11:27:10 EDT - Researchers have shown the ability to grow high quality, single-layer materials one on top of the other using chemical vapor deposition. This highly scalable technique, often used in the semiconductor industry, can produce new materials with unique properties that could be applied to solar cells, ultracapacitors for energy storage, or advanced transistors for energy efficient electronics, among many other applications.
Irrigated agriculture: precious habitat for the long-billed curlew
Wed, 16 Apr 2014 10:16:32 EDT - Despite the recent rainfall, California is still in a drought, so not only are water supplies limited, but demand for water is increasing from a variety of uses. In a recent study, scientists document the importance of irrigated agricultural crops in California's Central Valley to a conspicuous shorebird.
Using video surveillance to measure peoples' hand washing habits
Wed, 16 Apr 2014 10:16:30 EDT - Use of video surveillance to better understand essential hygiene behavior has been pioneered by researchers. Still, despite years of global public awareness campaigns, hand washing rates remain low. Caregivers of young children in low-income, developing world settings are found to wash their hands only 17 percent of the time after using the toilet. A new study finds that video surveillance can provide insights into hand washing behavior. Study findings could inform the design, monitoring and evaluation of hygiene campaigns.
Ant colonies help evacuees in disaster zones
Wed, 16 Apr 2014 10:16:25 EDT - An escape route mapping system based on the behavior of ant colonies could give evacuees a better chance of reaching safe harbor after a natural disaster or terrorist attack by building a map showing the shortest routes to shelters and providing regular updates of current situations such as fires, blocked roads or other damage via the smart phones of emergency workers and those caught up in the disaster.
How toddlers learn verbs: New insight
Wed, 16 Apr 2014 10:16:21 EDT - Parents can help toddlers' language skills by showing them a variety of examples of different actions, according to new research. Previous research has shown that verbs pose particular difficulties to toddlers as they refer to actions rather than objects, and actions are often different each time a child sees them.
Researchers propose network-based evaluation tool to assess relief operations feasibility
Wed, 16 Apr 2014 10:16:19 EDT - The United Nations Office for Disaster Risk Reduction reported that disasters have affected around 2.9 billion people worldwide from 2000-2012- killing more than a million, and damaging around 1.7 trillion US dollars in estimates. Moreover, natural disasters and their damages have been documented to occur with increasing intensity. Given the staggering numbers, effective disaster preparedness and relief response plans is compelling, especially considering the fact that natural disasters are usually unpredictable and damage cannot be avoided. Scientists have now presented a model that looks into the logistics of disaster relief using open data and tools and measures developed in the field of network science.
Global scientific team 'visualizes' a new crystallization process
Wed, 16 Apr 2014 10:16:17 EDT - By combining a synchrotron's bright X-ray beam with high speed X-ray cameras, scientists shot a 'movie' showing how organic molecules form into crystals. This is a first. Their new techniques will improve our understanding of crystal packing and should help lead to better electronic devices as well as pharmaceuticals -- indeed any product whose properties depend on precisely controlling crystallization.
Augmented Reality: Bringing History and the Future to Life
Wed, 16 Apr 2014 10:14:22 EDT - Have you ever wished you had a virtual time machine that could show you how your street looked last century? Or have you wanted to see how your new furniture might look, before you’ve even bought it? Thanks to new research you can now do just that.
Progress in understanding immune response in severe schistosomiasis
Wed, 16 Apr 2014 10:13:41 EDT - A mechanism that may help explain the severe forms of schistosomiasis, or snail fever, has been discovered by researchers. Schistosomiasis is one of the most prevalent parasitic diseases in the world. The study in mice may also offer targets for intervention and amelioration of the disease. Although schistosomiasis is not contracted in the United States or Europe, the World Health Organization reports that this neglected tropical disease is endemic primarily in Africa, but is also found in South America, the Middle East, and Asia.
